These Stölzle Lausitz Power White Wine Glasses require minimal setup: simply unbox, wash, and they are ready for use. They are compatible with a wide range of wines, primarily heavy white wines like Chardonnay and Pinot Grigio, but are also suitable for medium-weight red wines.For care and maintenance, these glasses are remarkably convenient: they are dishwasher safe. To maintain their brilliant clarity and prolong their life, it is recommended to place them securely in the dishwasher, avoiding overcrowding. Use a high-quality dishwasher detergent and, if available, a rinse aid, especially in areas with hard water. If hand washing, use warm, soapy water and a soft cloth, then dry immediately with a lint-free cloth to prevent water spots.
